WW Granger tends to be a little high on such items. A local machine shop supply house might be half the price.

I happen to be at Grizzly this week, will have to see if they stock such an item as well.

But what about the quality. I notice a BIG difference between my cheap H.F. set and my good Norseman drills. I am tired of the cheap stuff all these different names who has the quality.

I buy from these guys all the time. SUPER fast shipping and they have just about anything you want.

I haven't tried this particular drill but at least it's made in America, and the price is right.:wink:

One question though, isn't this drill a little big? My refills mic out at about .424". It seems to me that a 27/64 with MAYBE , or not, a little bit of filing would be a better choice. The 11.2mm would only leave .005" on the sides for threads.
I think I'll drill a 27/64" hole in a piece of scrap and see. I'll get back to ya'.:wink:
 
I tried a 27/64" bit and it worked just fine. I drilled it on my lathe and tried it and it was just a tad tight. 30 seconds with a round file with the lathe on and I had a perfect fit.
As far as the cap goes, I don't like gluing parts on a pen so I found a real slick solution. A #4 pan head sheet metal screw fits inside the cap PERFECTLY. I drilled the cap blank 3/4" deep with a letter "U" bit, it's a snug fit but that's good. I drilled a clearance hole in the cap for the screw and a pilot hole in the blank and then screwed it in by hand. I used 1/2" long screws because that's what I had but 3/8" should be long enough. It works like a charm and I don't have to worry about the cap coming off in a customers hand.:mad:
 
Rick,
I am having difficulty visualizing what you did with the screw and cap. Can you take a picture of it. I am a visual learner and can not get my head wrapped around the words to create a picture. Thanks I appreciate it.
 
Here you go Cindy................

Voila! I haven't tried turning one yet but I don't see any problem with putting a dead center inside the cap and turning. In fact it will cause the blank to be turned true to the cap which is what you want.:wink::biggrin:

Forgive my ignorance if this was posted in a different thread but what is this tap for? I know it says sharpie refill but is there a post that shows one of these being made?
 
Thank you Bruce - I would like to make some of those for Christmas but didn't see this group buy until after it was over. Was gone for a few months. Maybe next time.
 
Tapsize

If a 1/2x20 is working, you are either making a hole that is too lose, and will have slop, or, as flimsy as the threads are on the refill, you are rethreading the refill/destroying the refill to get it in.
 
Drill Bit Size - Final word . . .

Just curious, what is the FINAL word on the "best" size drill bit to buy to use with the taps that are coming. I have held off buying a drill bit to see what the consensus was on size.

Thanks
Steve
 
Drill Bit

I got the 11.2 in, i haven't used it. I'll try tonight and let you know if it's worth buying over the 7/16.
 
The wife . .

The wife tells me that my tap has arrived . . .

Thanks,
Steve

P.S. What's the verdict on the optimum size drill bit . . ?
 
Got mine too! Cindy, I don't know about consensus but I use a 27/64" bit. It's a few thou undersize but most of the time a drilled hole is a tad bigger anyway. If it's too snug I just hit it with a round file with the lathe on, takes about 30 seconds to get it right. The refill is tapered so you only have to enlarge the first 1/2" or so.:wink:
